While driving at 65mph the sunroof exploded. The shade was closed so no glass hit the occupants but it made a very loud noise. Audi replaced the sunroof at no charge citing "customer goodwill" as the reason for making the repair for free.

Air circulation fan in the dash board started making a very slight scraping noise. It wasn't very loud but the A6 is so quiet on the highway that I could hear the noise and after a while it became annoying. Audi replaced it at no charge.

Second trip to dealer to address harsh downshifting from 4th to 3rd and 3rd to 2nd. Unable to fix. They stated transmission has no fault codes and that the harsh shifting should go away as I continue to drive.

The vehicle has been sent several times to the workshop for rectification of sound from front right suspension without any results. Dealer continues to say there is not issue, whereas, the repairs were unsuccessful.

Car began shuttering/vibrating when braking (just like back at 9,000 miles when dealer replaced brakes/rotors under warranty). Was told pads still had 50% life left, but rotors needed replacing. Complained to dealer. Told to call Audi. Told the same thing. Then emailed Dealer Service Manager with all receipts and recent inspection report. Told to bring car back in. On inspection, only right front rotor was "scoring". Dealer replaced both front rotors and pads - No charge
